To insure freedom from failure on the part of the clutch dogs in operating the clutch I havefshown disk 25 o spring steel secured looselyby rivets 26 to` Y the outer member 27 nl the plate series 1, wliichhae 60 :in :muulur recess or groove 28 in its outer ind, Oppolite the region ol engagement by the' dogs 19. l

The (logs cnn be sci, up to crowd the spring disk nor` nmlly into the recess, adjustment being effected by rotnlinn of the carrier 2l on he bushing 6,111.11, dogs 65 nioving during such adjustment in un annular field cnrrcspomiing lo the dnnulzir recess 28,'nnd ordinary fric-tional wear of any oi the nulmeting parts will bc trillen up nutonw-ticnlly by the resiliency of the spring disk. 4ly the term dogs I mean yto designate :m3/.'70 Suiiaible deyice to pcrierm thc function served by the members lil l 1 I in operaiion, the collar-r 23 audits-'cene 22 is'thon'n to the leiL, spreads the m1115124 and crowdethe dogeI 19 against the dink 25, nud the plate series l, which is conheeled by the groove and entlier connectip with the bushing 6 on the shaft 3, imparts to the latter the xuctimi derived frein ille contacting plteseries'g, ibis series being actuated by the connecting yoke 4member lig'. upon he roiating drum 12, whieh ini-urn deriveeV 80 its motion from the shat member 29 through the me' diuin oi planetary genna 30 Unified by puslsl mounted 1o relate wiili ille hub 32 of lhe shaft member 3.

The post 31 is eonnecied with u boss 35 in the web Sli of ihn drum 1], which is further connected with the S5 'hub S2 by u. belt 37 and is supported by und rotates with ihe lnter, h-.wing an inner peripheral mck 38 with which ineslrpleneinry gears 3i) carried by posts L.i0 in bearings 41 upon ilu: well; 42 oi the drum 10.

Unun rotation of ih' shaft member 29, ibo shaft mem- 90 ber 3 will be operated at 10W speed il' the dogs 19 be released and die pulley 12 held froinroiaiion yby any trible nicnns,;no, shown, as ler example the devices illustmled und described in my application lor Letters Xntent Serial No. 239,161 ronrwhich thinpresentv applieatien has been divided, andl to which reference maybe made. v

Revenus :notion ni low speed of the inem4 bei 3 relatively zo the member 29 will be secured when the drum l() is held from ruintion, the drum 1,2 and z dogs 1Q beiuglrce. t i 105 lmve provided for an eiieien. dietribution of Oil to the various hearings, by forming a supply chamber 43, (plugged at 44) in the shaft member 3, which chamber i's in communication by a channel 45 in the bushing 46, a similar channel 47 in the bushing 48 and a channel 49 n the bushing 50, connected by a series of ports 51 communicating with the chamber' 52 within the drum 12 and through which the oil finds access to the mck 33 and gear 30, as Well :is to the post 3l by a. port 53 through the bushing 54.

Porte 56, 56 and 57 provide access for oil to the bushing-channels 58, 59 and (i0 respectively.

Having described my invention thus fully, und con vement means for carrying the same into effect, I do the specific means illustratori and nor in genral otherwise than as set forth in the claims read 1n connection with this specification.

What I claim and desire to secure by Letters Patent operative contact, said menus and pinten, substantially as described.
